Although she became famous on ‘Laguna Beach’ and ‘The Hills,’ Kristin told Hollywoodlife.com EXCLUSIVELY why she will never return her reality TV days.

Hollywoodlife.com spoke to Kristen at the The Bing It On Halloween Costume Challenge in New York, where she told us she will be dressing up Camden as a lion!

“He is a Leo, so it makes sense,” she said. But don’t expect camera crews to capture her life as a mommy anytime soon. The 25-year-old said she and fiance Jay Cutlerwould “never” star in a reality show.

“My family is too precious to me,” the new mom said.

“A lot of relationships and friendships I had during The Hills and Laguna Beach were ruined, so I would never risk that with my family,” she added.
